The total construction bill for Grand Inga has been calculated to be as high as $80 billion. The World Bank, the European Investment Bank and the African Development Bank, have provided funding for feasibility and environmental impact studies. In 2016, the World Bank cancelled its support for the Grand Inga Project, but reconsidered Inga 3 in 2024. It is expected that the power stations will be developed as a public private partnership project.

In June 2020, the Government of the Democratic Republic of the Congo resolved to present the project to the regional heads of State and explore the market on the continent for the power generated. They have recruited the African Union and the New Partnership for Africa's Development in their efforts to get the power station built. South Africa has indicated willingness to buy 2.5 GW of the dam's output. Nigeria is interested in buying 3 GW and the Congolese mines in Katanga Province are interested in 1.3 GW.[
